HANK: That call I got telling me Marie was in the hospital. That wasn't Pinkman. You had my cell number.

When Hank tracked down Walt and Jesse’s RV in Season 3’s “Sunset”, things looked pretty bleak for the duo. So Walt got Saul Goodman’s assistant to pretend to be a hospital worker and tell Hank that Marie was in critical condition after a car crash, forcing him to leave the scene. It worked, but it was one of Walt’s slimiest moves of the series.
